How can I encode a video to play on a DLink DSM-520 using FFMPEG ?
4 octobre 2015, par tolsen64I have been searching, testing, and coming up with nothing for over a week. I want to use FFMPEG to convert mp4’s and mkv’s to AVI files that will play on my DLink DSM-520. Mencoder will do it. The files that FFMPEG generates cause the player to lock up less than a minute into the video. First, here’s what I use to encode the file using Mencoder (scraped from the test.bat file that PocketDIVXEncoder generates :
mencoder.exe ftwd105.mp4 -af volnorm -srate 44100 -oac mp3lame -lameopts mode=0:cbr:br=128 -noodml -vf pp=ac,scale=720:404,crop=720:400,harddup -sws 9 -ovc lavc -lavcopts vcodec=mpeg4:mbd=1:last_pred=2:vstrict=1:threads=2:vmax_b_frames=0:vbitrate=1200 -ffourcc XVID -o ftwd105_HDTV.avi
The output file plays perfectly on the DSM-520. Looking at the file using FFPROBE, I see this :
Input #0, avi, from 'ftwd105_HDTV.avi':
Metadata:
encoder : MEncoder Redxii-SVN-r37527-4.9.3 (x86_64)
Duration: 00:44:32.96, start: 0.000000, bitrate: 1193 kb/s
Stream #0:0: Video: mpeg4 (Simple Profile) (XVID / 0x44495658), yuv420p, 720x400 [SAR 1:1 DAR 9:5], 1053 kb/s, 23.98 fps, 23.98 tbr, 23.98 tbn, 24k tbc
Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 44100 Hz, stereo, s16p, 128 kb/sSo now I try the same thing with FFMPEG.
ffmpeg -i ftwd105.mp4 -vcodec mpeg4 -vtag XVID -b:v 1200k -s 720x400 -acodec libmp3lame -ab 128k -ar 44100 -ac 2 -f avi ftwd105_ffmpeg.avi
This file does not play on the media player. It plays choppy with only clicking for sound for about 15-30 seconds, then it freezes. Looking at it with FFPROBE, it looks exactly the same as the one created by Mencoder.
Input #0, avi, from 'ftwd105_ffmpeg.avi':

Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 44100 Hz, stereo, s16p, 128 kb/sSo now I encode the video using Xvid4PSP. It plays perfectly fine and FFPROBE shows this :
Input #0, avi, from 'ftwd105_ps2.avi':
Metadata:
encoder : VirtualDubMod 1.5.10.3 | www.virtualdub-fr.org || (build 2550/release)

Stream #0:0: Video: mpeg4 (Advanced Simple Profile) (XVID / 0x44495658), yuv420p, 720x400 [SAR 1:1 DAR 9:5], 723 kb/s, 23.98 fps, 23.98 tbr, 23.98 tbn, 23.98 tbc
Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 48000 Hz, stereo, s16p, 128 kb/sIt’s using Advanced Simple Profile so I look this up and change my FFMPEG options :
ffmpeg -i ftwd105.mp4 -vcodec mpeg4 -vtag XVID -b:v 1200k -s 720x400 -profile:v 15 -level 0 -acodec libmp3lame -ab 128k -ar 44100 -ac 2 -f avi ftwd105_ffmpeg.avi
But though the output file looks the same using FFPROBE as the one made by Xvid4PSP, it still doesn’t play on the DSM-520.
Input #0, avi, from 'ftwd105_ffmpeg_asp.avi':
Metadata:
encoder : Lavf57.0.100

Stream #0:0: Video: mpeg4 (Advanced Simple Profile) (XVID / 0x44495658), yuv420p, 720x400 [SAR 1:1 DAR 9:5], 1165 kb/s, 23.98 fps, 23.98 tbr, 23.98 tbn, 24k tbc
Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 44100 Hz, stereo, s16p, 128 kb/sSo now i’m at a loss. Is FFMPEG incapable of generating a file that the DSM-520 can play ? The reason I want to use FFMPEG over Mencoder is that it’s much faster. What takes FFMPEG 15 minutes takes Mencoder 40.
I should note that all the files created by FFMPEG play fine on the PC and on my Visio television. The DSM-520 is hooked up to a bedroom tv that isn’t a smart tv.
Edit : I also tried libxvid in place of mpeg4 with the same results.

Equalizers, bassboost and reverb effect not working (using FFmpegMediaPlayer)
9 février 2018, par ArrenI’m currently using FFmpegMediaPlayer from github and the effects are not working in the phone but works perfectly in the emulator which of both are the same API 22.
The strange thing is that when I switch the code from FFmpegMediaplayer to standard android media player the effects start working again in the real phone device. But when I switch back to ffpmeg the effect only works in the emulator and not in the real device. My code is as below,
public void setupVisualizerFxAndUI() {
try {
mVisualizer = new Visualizer(mMediaPlayer.getAudioSessionId());
mEqualizer = new Equalizer(0, mMediaPlayer.getAudioSessionId());
mEqualizer.setEnabled(true);
try {
bassBoost = new BassBoost(0, mMediaPlayer.getAudioSessionId());
bassBoost.setEnabled(false);
BassBoost.Settings bassBoostSettingTemp = bassBoost.getProperties();
BassBoost.Settings bassBoostSetting = new BassBoost.Settings(bassBoostSettingTemp.toString());
bassBoostSetting.strength = (1000 / 19);
bassBoost.setProperties(bassBoostSetting);
mMediaPlayer.setAuxEffectSendLevel(1.0f);
presetReverb = new PresetReverb(0, mMediaPlayer.getAudioSessionId());
presetReverb.setPreset(PresetReverb.PRESET_NONE);
presetReverb.setEnabled(false);
mMediaPlayer.setAuxEffectSendLevel(1.0f);
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
if (homeActivity.isEqualizerEnabled) {
try {
bassBoost.setEnabled(true);
BassBoost.Settings bassBoostSettingTemp = bassBoost.getProperties();
BassBoost.Settings bassBoostSetting = new BassBoost.Settings(bassBoostSettingTemp.toString());
if (homeActivity.bassStrength == -1) {
bassBoostSetting.strength = (1000 / 19);
} else {
bassBoostSetting.strength = homeActivity.bassStrength;
}
bassBoost.setProperties(bassBoostSetting);
mMediaPlayer.setAuxEffectSendLevel(1.0f);
if (homeActivity.reverbPreset == -1) {
presetReverb.setPreset(PresetReverb.PRESET_NONE);
} else {
presetReverb.setPreset(homeActivity.reverbPreset);
}
presetReverb.setEnabled(true);
mMediaPlayer.setAuxEffectSendLevel(1.0f);
} catch (Exception e) {
e.printStackTrace();
}
}
if (homeActivity.isEqualizerEnabled && homeActivity.isEqualizerReloaded) {
try {
homeActivity.isEqualizerEnabled = true;
int pos = homeActivity.presetPos;
if (pos != 0) {
mEqualizer.usePreset((short) (pos - 1));
} else {
for (short i = 0; i < 5; i++) {
mEqualizer.setBandLevel(i, (short) homeActivity.seekbarpos[i]);
}
}
if (homeActivity.bassStrength != -1 && homeActivity.reverbPreset != -1) {
bassBoost.setEnabled(true);
bassBoost.setStrength(homeActivity.bassStrength);
presetReverb.setEnabled(true);
presetReverb.setPreset(homeActivity.reverbPreset);
}
mMediaPlayer.setAuxEffectSendLevel(1.0f);
} catch (Exception e) {
e.printStackTrace();
}
}where mMediaPlayer is ffmpeg...Other than that the library is working fine in regards to streaming. The only problem is that it doesn’t get any effect put in. I thought this might be a coding problem so I just switched ffmpeg with Android standard media player like I mentioned above and it works. FFmpeg - bass boost and equalizer only works in the emulator and not in real phone device.
Another strange thing was that the effect initially worked at first in debug run mode and stopped working after I signed the apk. From which point on it stopped working both in the debug as well as any other run modes i.e - release also....I’m not using any pro guard rules also.
Points to note :
1. Replacing FFmpegmediaplayer with Standard Media player the effects works.
2. Effects worked before signing the apk then stopped working in all run modes
3. Using the same code above for FFMpegmediaplayer effects only work in the
Emulator and not in real device.
4. Other than the effects problem, FFmpegmediaplayer is functional regarding
streaming and local playback - in real phone device as well as emulator. -
