  • Record video with Media Recorder in WEBM format

    21 mai 2017, par Matho

    I need to record two videos via media recorder and process them with ffmpeg in Android. I want to read videos via pipe in ffmpeg command string. From what I have read, I could not use 3GPP/MP4 format, because these formats contains header at the end of video. Because of it, I want to use WEBM video format, but my app is crashing, when I use webm/vp8 setting in media recorder. Ffmpeg I’m using is : com.writingminds:FFmpegAndroid:0.3.2. Could you help me please ?

[mpeg4 @ 0x2fe5700] Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using the mpeg4_unpack_bframes bitstream filter without encoding but stream copy to fix it.
    
[h264_qsv @ 0x2fce7c0] Encoder will work with partial HW acceleration

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

Conversion failed!

    It seems like that something of parameter missing, I think.

    If you have an idea to solve this, let me know.

    Bests,
