Illegal instructionThe result is an empty out.MP4 file... I’ve tried different configuration but never got it to work.
the one minute input file i’m using to test can be downloaded from https://dl.dropboxusercontent.com/s/dxd285zrz6d57da/GOPR2546.MP4
Thank you all in advance !!

Using libav to encode RGBA frames into MP4 but the output is a mess
5 octobre 2019, par Cu2SI’m trying to decode a video into RGB frames, and then postprocess the frames, finally encode the frames into a video. But the output video is completely a mess :
I wrote a minimal example to illustrate my idea. First, I read some information from some source video :
AVFormatContext* inputFormatCtx = nullptr;
int ret = avformat_open_input(&inputFormatCtx, inputParamsVideo, nullptr, nullptr);
assert(ret >= 0);
ret = avformat_find_stream_info(inputFormatCtx, NULL);
av_dump_format(inputFormatCtx, 0, inputParamsVideo, 0);
assert(ret >= 0);
AVStream* inputVideoStream = nullptr;
for (int i = 0; i < inputFormatCtx->nb_streams; i++)
{
const auto inputStream = inputFormatCtx->streams[i];
if (inputStream->codec->codec_type == AVMEDIA_TYPE_VIDEO)
{
inputVideoStream = inputStream;
break;
}
}
assert(inputVideoStream != nullptr);
AVCodecParameters* inputParams = inputVideoStream->codecpar;
AVRational framerate = inputVideoStream->codec->framerate;
auto gop_size = inputVideoStream->codec->gop_size;
auto maxBFrames = inputVideoStream->codec->max_b_frames;Then I assign the information to the output stream :
AVFormatContext *outputAVFormat = nullptr;
avformat_alloc_output_context2(&outputAVFormat, nullptr, nullptr, kOutputPath);
assert(outputAVFormat);
AVCodec* codec = avcodec_find_encoder(outputAVFormat->oformat->video_codec);
assert(codec);
AVCodecContext* encodingCtx = avcodec_alloc_context3(codec);
avcodec_parameters_to_context(encodingCtx, inputParams);
encodingCtx->time_base = av_inv_q(framerate);
encodingCtx->max_b_frames = maxBFrames;
encodingCtx->gop_size = gop_size;
if (outputAVFormat->oformat->flags & AVFMT_GLOBALHEADER)
encodingCtx->flags |= AV_CODEC_FLAG_GLOBAL_HEADER;
AVStream* outStream = avformat_new_stream(outputAVFormat, nullptr);
assert(outStream != nullptr);
ret = avcodec_parameters_from_context(outStream->codecpar, encodingCtx);
assert(ret >= 0);
outStream->time_base = encodingCtx->time_base;Then I convert RGBA frames(which is read from files) into YUV420P via
sws_scale, and encoding :ret = avcodec_open2(encodingCtx, codec, nullptr);
assert(ret >= 0);
av_dump_format(outputAVFormat, 0, kOutputPath, 1);
ret = avio_open(&outputAVFormat->pb, kOutputPath, AVIO_FLAG_WRITE);
assert(ret >= 0);
ret = avformat_write_header(outputAVFormat, nullptr);
assert(ret >= 0);
AVFrame* frame = av_frame_alloc();
frame->width = inputParams->width;
frame->height = inputParams->height;
frame->format = inputParams->format;
frame->pts = 0;
assert(ret >= 0);
ret = av_frame_get_buffer(frame, 32);
int frameCount = 0;
assert(ret >= 0);
ret = av_frame_make_writable(frame);
assert(ret >= 0);
SwsContext* swsContext = sws_getContext(inputParams->width, inputParams->height,
AV_PIX_FMT_RGBA, frame->width,
frame->height, static_cast<avpixelformat>(inputParams->format),
SWS_BILINEAR, NULL, NULL, NULL);
for (auto inputPicPath : std::filesystem::directory_iterator(kInputDir))
{
int width, height, comp;
unsigned char* data = stbi_load(inputPicPath.path().string().c_str(), &width, &height, &comp, 4);
int srcStrides[1] = { 4 * width };
int ret = sws_scale(swsContext, &data, srcStrides, 0, height, frame->data,
frame->linesize);
assert(ret >= 0);
frame->pts = frameCount;
//frame->pict_type = AV_PICTURE_TYPE_I;
frameCount += 1;
encode(encodingCtx, frame, 0, outputAVFormat);
stbi_image_free(data);
}
while (encode(encodingCtx, nullptr, 0, outputAVFormat))
{
;
}
static bool encode(AVCodecContext* enc_ctx, AVFrame* frame, std::uint32_t streamIndex,
AVFormatContext * formatCtx)
{
int ret;
int got_output = 0;
AVPacket packet = {};
av_init_packet(&packet);
ret = avcodec_encode_video2(enc_ctx, &packet, frame, &got_output);
assert(ret >= 0);
if (got_output) {
packet.stream_index = streamIndex;
av_packet_rescale_ts(&packet, enc_ctx->time_base, formatCtx->streams[streamIndex]->time_base);
ret = av_interleaved_write_frame(formatCtx, &packet);
assert(ret >= 0);
return true;
}
else {
return false;
}
}
</avpixelformat>Finally I cleaned up stuff :
av_write_trailer(outputAVFormat);
sws_freeContext(swsContext);
avcodec_free_context(&encodingCtx);
avio_closep(&outputAVFormat->pb);
avformat_free_context(outputAVFormat);
av_frame_free(&frame);I dumped my input format and my output format :

Reverse and areverse crash the computer
14 août 2019, par AlexI am using this command :
ffmpeg -y -ss 00:03:52.612 -i "H:\DCIM\100GOPRO\GOPR3258.MP4" -r 60 -t 00:00:12.140 -vf reverse -af afade=t=in:ss=0:d=1,afade=t=out:st='00\:00\:11.140':d=1,areverse 6.mp4It increases the memory consumption of the computer to a point of collapse.
Putting it like
ffmpeg -y -ss 00:03:52.612 -i "H:\DCIM\100GOPRO\GOPR3258.MP4" -r 60 -t 00:00:12.140 -af afade=t=in:ss=0:d=1,afade=t=out:st='00\:00\:11.140':d=1 6.mp4Works without a problem.
Therefore, the issue is in the
-vf reverseand-af reverse.The output is
